    <p>My request's header is application/json but my response's header is application/xml. How can I change my response header to application/json?</p> <p>Request Header:</p> <blockquote> <pre><code>"Accept-Encoding" = gzip; "Content-Length" = 21; "Content-Type" = "application/json"; "User-Agent" = "BarcodeReader 1.0 (iPhone Simulator; iPhone OS 7.0.3; en_US)"; </code></pre> </blockquote> <p>Response Header:</p> <blockquote> <pre><code>"Cache-Control" = private; Connection = close; "Content-Length" = 689; "Content-Type" = "application/xml; charset=utf-8"; Date = "Mon, 09 Dec 2013 06:45:32 GMT"; Server = "Microsoft-IIS/7.5"; "X-AspNet-Version" = "4.0.30319"; "X-Powered-By" = "ASP.NET"; </code></pre> </blockquote> <p>The code:</p> <pre><code> ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:@"http://wcftest.amerikanhastanesi.org/BarkodIOS.svc/rest/HastaAra"]]; NSData *myPostData = [[NSString stringWithFormat:@"{\"protokolNo\":%d}",protokolNo] dataUsingEncoding:NSUTF8StringEncoding]; NSMutableData *myMutablePostData = [[NSMutableData alloc]initWithData:myPostData]; [request setPostBody:myMutablePostData]; [request setRequestMethod:@"POST"]; [request addRequestHeader:@"Content-Type" value:@"application/json"]; [request setDelegate:self]; [request startSynchronous]; NSLog(@"%@",[request responseHeaders]); NSLog(@"%@",[request requestHeaders]); id jsonObjects = [NSJSONSerialization JSONObjectWithData:[[request responseString] dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:nil ]; HastaModel *h; for(NSDictionary *theItem in [jsonObjects objectForKey:@"HastaAraResult"]){ h = [[HastaModel alloc]initWithDictionary: theItem]; } return h; </code></pre> <p>Please don't ask me to use ASIFormData instead of using ASIHTTPRequest.

    1. COWhat is responding? It's not related to iOS or objective-c. The web server has to add the Content-Type header to the response.

    2. COI modified MIME but didn't work. Then I add [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] to cs and it didn't work also. So I think it's the code problem.

    3. COPlease can you edit your question to include the code you are using to generate the HTTP response (and specifically the header for that response).

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
